1, 2, 3, Go!

[BrotherKinsMan]

One.

It all started with One.

One and all; One and only.

The original all knowing One.


Two.

On and off.

Up and down.

Left and right.

Blue and Red.

This and that.

Me and you.

Balance must be even.


Three.

Now we're playing.

Chaos dwells at home.

Balance can be kept unevenly.

Or foregone entirely.

Three as One.

The Trinity.

Three.


And the rest is history.

What's the last number!?

The first is One.

“One is the loneliest number”
Song just came to mind when reading 

Thinking one must be three to be complete

[UltraBudgie]

Numbers don't exist. As soon as we started pretending they do, that's when things started going futzy. Big mistake. Before you know it, boom! Statistics, compound interest, and other horrors.

Oh, and the same with "probability". Sure, Mr Science Man. Go pedal that tripe somewhere else. I ain't never seen nothing that 25% happened.

I ain't never seen nothing that 25% happened.

Yeah, I was watching an old NASA launch on video the other day.  From zero to 100% of engine ignition I stopped the video at 25% ignition.  That was the point at which 25% ignition existed.

It happened.

Three.

And the rest is history.

What's the last number!?

Tao Te Ching 42 goes:
1, 2, 3, 10000

"The 10,000 things all carry yin and embrace yang.
They reach harmony by blending with ch'i."
